Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed April 12, 1902. Serial No. 102,653.

1'0 aZZ whowt it may concern:

Be it known that I, HENRY B. SARGENT, of the city and county of NewHaven, State of Connecticut, have invented a new and useful Improvementin Hinges, of which the following is a full, clear, and exactdescription when taken in connection with the accompanying drawings,which form a part thereof, and in which Figure 1 represents a frontelevation of the hinge embodying my invention; Fig. 2, a verticalsection on lines 2 2 of Fig. 1; Fig. 3, a central vertical sectionthrough the washers; Figs. 4 and 5, top views of the washers, and

Fig. 6 a bottom view of the retaining-sleeve.

In all figures similar letters of reference represent like parts.

This invention relates to hinges, and more particularly to the classknown as antifrictionhinges, and has for its object the production of anovel, simple, and effective antifriction device applicable in its useto a hinge or similar article.

One feature of the invention is the uniting or holding of the variousparts of the antifriction device in a single unitary structure which maybe removed by itself from the hinge or other article; and the inventionconsists in this and other improvements and combinations of parts setforth and claimedhereinafter.

Referring to the drawings for a more particular description, the partsdesignated by the letters A and B represent the two leaves of a hinge,of which a and 6 represent the respective knuckles.

C is the pintle of the hinge.

D and E designate a pair of washers adapted to fit between the knucklesa and 6. In one of the washers, as D, is an annular groove or recess dfor a series of balls F. The washer D is provided with a circularperforation cl, and G is a sleeve the lower end of which fits into saidperforation CZ, and when so assembled the outer surface of the sleeveforms the inner face of the recess d for the balls. Near the upper endof the sleeve G its outer surface is outwardly tapered, as shown at 9,so that when assembled the upper end projects slightly over the balls,thereby retaining them in position in the recess (Z. The washerE isprovided with a circular perforation a, into which the upper end of thesleeve G fits, and when so assembled the washers are held in theirrelative positions by the sleeve G.

A11 axial perforation g in the sleeve G is adapted to receive thepintle, and the device is assembled in the hinge by placing it betweenthe knuckles and inserting the pintle through the knuckles and aXialperforation g of the sleeve G.

By the withdrawal of the pintle the washer and balls may be removed fromthe hinge as a single unitary structure, and the balls will remain inplace until the sleeve Gris removed from the washer D.

Having now described my invention, (which may vary somewhat in itsdetails without departing from the spirit thereof,) what I claim, anddesire to secure by Letters Patent, is

The combination with a hinge; of a pintle; a pair of washers adapted tofit between the knuckles of said hinge, one of said washers having anannular channel; a series of balls in said channel, and a sleeve formingthe inner side of said channel and being adapted to receive said pintle,said washers and sleeve being removable as a unitary structure from saidhinge upon the extraction of said pintle, and said washers being heldtogether, when removed, by means of said sleeve; substantially asdescribed.

In witness whereof I have hereunto set my hand on the 8th day of April,1902.

HENRY B. SARGENT.
